' is arranged to indicate the requiredfcutsi or rafters'and for stairsand for various other similar uses.

-- "A further object of any invention' is to provide a combination tool of this character which is extremely sturdy and which maybe adjusted very closely and yet one which-can be folded compactly into 'a very small space, which when folded maybe conveniently carried about. All other tools of this character with which I am familiar, cannot be'convem iently carried about, and thus are usually left I in the tool kit and thus are not used as often as they might be forthe reason thatth'e carpenter'or builder must leave the place where 29 he is working, go to his tool-kit andretu'rn with the device before he can use'the same.

Often, rather than do this, he will calculate the desired angle or length rather than take the time to procure the instrument. I attain these and other objects by means of an instrument comprising a straight-edge formed on one'of'its edges with oppositely projecting flanges normal to the said straight edge, and two arms each pivoted at one end to the straight-edge at a common point, one ofsaid arms being provided with a slidable extension, said arms being correspondingly graduated, and the ends of said arms adjacent said common pivotal point being'provided with a notch, respectively, said notches arranged to register when said arms are-arranged normally to each other, a locking-pin movable on said straight-edge, adapted 'tobe inserted in said notches'when placed in registration, and braces ,pivotally connected at one end to each of said arms, .thevopposite ends of said braces being movably connected,

My vtool comprises a straight edge a in which are arms-b and'c pivoted at ,a common point; A brace d is pivotally' connected at one of'itsends cl to th'eearb'iormed on the arm I) andis slidably fastened at its other end d to the body athrough the-slot 6., A

tightening nut f is provided on the pin f by which said "connection is made so that; the brace can, beheld inset position by tighteningasaid nut. -A second brace g is pivotally supported at its end g to the ear 0 formed on the arm 0 and is slidably connected at its opposite end to the body a through the slot h. In this brace also a lock nut i is provided on a pin 71 which slides into said slot it, said nut being provided to hold the arm in set position in the slot. Said slots 6 and it have no definite form, butare merely arranged to permit the arms I) and 0 to fold within the body. a and the scales at each side thereof have been marked on the body when the arms;

have been set tothe desired angle. In other words, the slots and scales are not computed so that the arms will make definite angles with each other or with the body, but are right angle with said sidesu and a respectively. The ends are partially closed, as shown in Figs. 2 and 3, space being provided for the arms 6 and cto extend slightly beyond said ends, as shownin- Fig. 3, so that they can be grasped when said arms are folded into said body. Indicators j and m are carried by the pins f and i, respectively. The indicator is adapted toregister with the scale Z alongside the slot 6 and the indicator m is adapted to register with the scales n or n at each side of the slot h. For this purpose, the indicator m is provided with two points, one of which is adapted to register with the scale n" and the other with the scale being a' relatively fixed pivot. The arm I) at the'pivoted end is made of a single thickness of material and the arm 0 of two thicknesses spaced apart at its pivoted end thus permitting the arm 5 to be mounted within the arm 0, as is indicated in Figs. 10 andll.

The arm 5 islongitudinally extensible, being provided with a head portion 6 of one thickness of material. The arm 6 is provided with a slot 5 and said head portion is pro vided with a locking device If which extends through said slot. The locking device is longitudinally slidablein the head 6 and is pro- The head portiondirectly. above said teethis vided 'with two beveled gripping. pbints b v onsprovided with two inturned flanges b which are adapted to be engaged by said points 5 and are adapted to be moved towards each other so as to clamp the arm 6 between them in a desired position in the slot 6 Said clamping action tends to clamp the part 5" over theblade and thus holds the head 5 in set position. The arm 0 is made up, as before mentioned, of two members 0 which are spaced apart and between which the blade 0 is fixed The slidable head 6 of the arm 6 carries a scale p and the blade 0 of the arm a is provided with a corresponding scale 9. The endsrof said arms Z) and 0 below the pivot 0 are provided with notches b andc respectively. Said notches are arranged so that they extend an equal distance from the pivot 0 and are substantially radial relative thereto. Said notches move over a slot 1" which has a portion 9* concentric to the pivot point 0. The remainder r of saidslot-is at substantially right angles to said portion r. A

button 8 is slidably mounted in said slot r and is provided with heads 8 at each side of the body a to prevent said button from being removed from said slot. If it is desired to move the arms I) and 0 independently of each other, the button is arranged so as to lie within the portion r of the slot, but ifit is desired to lock said arms relative to each other at right angles, the arms are adjusted so that the notches 0 and b coincide with the portionr The button is then pushed into said notches and in this position the arms are locked so that they are held against relative movement with each other.

My combination tool as before mentioned has=;a number: of uses, the details of the application of which I will now explain.

As a space divider, any space may be divided with my combination tool into a desired number of 'equalparts, within the scope of the graduations on the arms I) and 0. The arm I), is longitudinally extended and the space to be divided is reduced to a scale of one foot to one inch and laid off between the sides of the angle formed by the said arms at the opposite numbers 12, on the scales p and 7 The number of divisions desired is then measured directly in inches between the arms .1) and 0- at thevrnumber of the scales p and 9 corresponding to the number of desired di- For example, if 12 feet is to be divided into twenty-four equal parts, the arms Z), 0 are adjusted until the space between them at the numbers 12 on each scale p, Q will be twelve inches" and then the space between the arms 1- at the numbers 24 on the said scale is measured,- which will be six inches, the dimension cffleach division? By reference to the geometrical: theorem that, similar triangles are to each otherias thematios of their: jcorresponding sides, the truth of this conclusion will be readily understood.

As a rafter miter the arms 6 and c are set at right angles by the bolt 8 as before mentioned and for determining the cuts of jack H and common rafters the arm and the main member Wlll indicate the slde and plumb cut.

- The indicator dis set at the desired pitch on the scale a as for instance an 812 pitch, the indicator will be set at 8 and similarly for other pitches. V

For the side cuts for hip or valley rafters the arm b will be set by the indicator j on the scale Z for the desired pitch as in the case above, andthe side cut will be indicated by i the arm I) and the brace 03. r

The plumb cut for hip and valley rafters will be indicated by the arm I; and the main member.

- The side and plumb cuts for cripple rafters are indicated by the brace g and the armo, V

the pitch of the roof being set as before mentioned on the scale a.

, The scale a" on the groove h is provided to give the miter cuts for the sheeting of a roof, the cuts being determined by the angle formed by the arm 0 and the main member a.

' f and 11.

The actual number of uses towhich my zsircombination tool may be set isv only limited 1 by the number of conditions which a builder As abevel square and try square, one arm ,may be folded away, and the other set for the.

desired bevel or rightangle or both arms I) and 0 may beclamped for the desired angle by the braces cl and 'g, and the thumb nuts may encounter in the course of his work. As

for instance, my tool may be used to lay 011' the miters for a regular polygon of any number of sides, it only being necessary for the builder to know the ratio or pitch of any two adjacent sides.
